to catch the Basic Idea of Domain and Range
Sample Quesitons of Domain and Range, Relations
1.Determine the domain of the Relation: {(0,2),(-2,-4)(-6,-3)}
The way the problems are set up are the value on the left is a X Coordinate and the Right is the Y Coordinate,
Because we know that the X coordinate is the domain and the Y Coordinate is the Range then the answer is Domain= {0,-2,-6}
2. Determine the domain and range of the realtion: {(x,y) l 3x<18}
First e want to solve the inquality so 3x<18 we would divide the problem by
3 so that the inequality would equal x<6, a easy way to see what you solved is
to put it on a number line like the example hear
Therefore the answer is { X l X < 6 }; Range = { Y l Y is a real number }
when the range or domain is infinite you could say that Range= All reals or vise versa
Hopefully the wiki is to some use to you, Hope you learnt something.
